Bone-Inspired Bending Soft Robot.

Soft robotics Jul 17, 2020
Bending soft robots must be structured and predictable to be used in applications such as a grasping hand. We developed soft robot fingers with embedded bones to improve the performance of a puppetry robot with haptic feedback. The manufacturing proc...

Fixed-time synchronization of stochastic memristor-based neural networks with adaptive control.

Neural networks : the official journal of the International Neural Network Society Jul 10, 2020
In this study, we consider the fixed-time synchronization problem for stochastic memristor-based neural networks (MNNs) via two different controllers. First, a new stochastic differential equation is established using differential inclusions and set-...

Sparse coding with a somato-dendritic rule.

Neural networks : the official journal of the International Neural Network Society Jun 26, 2020
Cortical neurons are silent most of the time: sparse activity enables low-energy computation in the brain, and promises to do the same in neuromorphic hardware. Beyond power efficiency, sparse codes have favourable properties for associative learning...
